Design and Analysis of a Dual-system Handheld Gadget for Automatic Pre-acceptance Checking of Substation Information
In order to improve the efficiency in pre-acceptance checking of substation equipment information and facilitate the construction of centralized control systems,a handheld gadget for automatic pre-acceptance checking of substation in-formation acceptance combining dual systems of smart grid control(D5000)and new centralized control was designed.First the current worldwide status and shortcomings of automatic pre-acceptance checking of substation information were clarified.Then three technical solutions,i.e.,the display of D5000 dual plane signal verification results,the automated pre-acceptance checking and result display of monitoring signals in the new centralized control system,and the differential display of signal cross-sections between the new centralized control system and D5000 system,were studied by analyzing working principle of the handheld gadget.A substation automatic pre-acceptance checking platform was built in Zone Ⅲ,and the handheld gadget was applied to the automatic platform by utilizing mobile software of i-State Grid.Finally the functionality and hardware design of the handheld gadget,and the formulation of its standardized workflow,were carried out.
